Portrait camera with horizontal/vertical mode viewfinder
Abstract
A portrait camera is intended to be used for picture-taking in a horizontal
orientation and in a vertical orientation. When the camera is oriented
horizontally, two head-finder circles or the like are visible in the field
of view of the viewfinder to frame the respective heads of two people.
When the camera is oriented vertically, only one of the head-finder
circles is visible in the field of view of the viewfinder to frame the
head of one person. Thus, two people are to be photographed when the
camera is oriented horizontally, but only one person is to be photographed
when the camera is oriented vertically.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates generally to the field of photography cameras, and
specifically to camera viewfinders.
2. Description of the Prior Art
When taking a picture it is necessary to know not only in what direction to
aim the camera but also how much of the subject(s) will be included in the
picture. For this reason practically every camera has a viewfinder of some
kind.
Viewfinders built on to or into portrait-like cameras are usually intended
to be used with the camera in a horizontal orientation for picture-taking.
No distinction is made in the viewfinder for positioning the camera in a
vertical orientation for picture-taking.
SUMMARY OF THE INVENTION
According to the invention, there is provided an improved camera wherein a
viewfinder has a field of view for viewing a subject to be photographed
when said camera is in one orientation or is in another orientation, and
wherein the improvement comprises:
first and second frame means for framing at least respective parts of
individual subjects to be photographed;
means for making the first frame means visible in the field of view of the
viewfinder regardless of whether said camera is in one orientation or
another orientation; and
means for alternatively making the second frame means visible in the field
of view of the viewfinder when the camera is in one orientation and not
visible in the field of view when the camera is in another orientation,
whereby two subjects are to be photographed when the camera is in one
orientation and only one subject is to be photographed when the camera is
in another orientation.
More specifically, a portrait camera is intended to be used for
picture-taking in a horizontal orientation and in a vertical orientation.
When the camera is oriented horizontally, two head-finder circles or the
like are visible in the field of view of the viewfinder to frame the
respective heads of two people. When the camera is oriented vertically,
only one of the head-finder circles is visible in the field of view of the
viewfinder to frame the head of one person. Thus, two people are to be
photographed when the camera is oriented horizontally, but only one person
is to be photographed when the camera is oriented vertically.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a front perspective view of a portrait camera according to a
preferred embodiment of the invention;
FIG. 2 is a front elevation view of a viewfinder in the portrait camera,
showing the field of view of the viewfinder when the camera is in a
horizontal orientation; and
FIG. 3 is a front elevation view similar to FIG. 2, showing the field of
view of the viewfinder when the camera is in a vertical orientation.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The invention is disclosed in connection with a 35 mm camera. Because such
a camera is widely known, this description is directed in particular to
photographic elements forming part of or cooperating directly with the
invention. It is to be understood, however, that other elements not
specifically shown or described may take various forms known to persons of
ordinary skill in the art.
Referring now to the drawings, FIG. 1 depicts a portrait-type camera 1
wherein a camera body 3 includes a direct see-through viewfinder tunnel 5
having front and rear rectangular openings 7 and 9, and a forwardly
protruding taking-lens snout 11. An electronic flash unit 13 is located
inwardly at one end of the camera body 3 beneath a pivotally supported
flash reflector/flash cover 15.
According to the invention, the portrait camera 1 is intended to be used
for picture-taking in a horizontal orientation and in a vertical
orientation. When the camera body 3 is oriented horizontally, two
head-finder circles 17 and 19 (or the like) are visible in the field of
view 21 of the viewfinder tunnel 5 to frame the respective heads of two
people. See FIG. 2. When the camera body 3 is oriented vertically, only
one of the head-finder circles 17 is visible in the field of view 21 of
the viewfinder tunnel 5 to frame the head of one person. See FIG. 3. Thus,
two people are to be photographed when the camera body 3 is oriented
horizontally, but only one person is to be photographed when the camera
body is oriented vertically.
The head-finder circle 17, as shown in FIG. 1, is fixedly supported on the
taking lens snout 11. If one looks through the viewfinder tunnel 5 at the
rear opening 9, the head-finder circle 17 appears to be off-center in the
field of view 21 towards one side 22 of the field of view. See FIGS. 2 and
3.
The head-finder circle 19 is supported for swinging movement about a pivot
pin 23 into and out of the viewfinder tunnel 5 through a slit (not shown)
in the bottom of the viewfinder tunnel. Specifically, the pivot pin 23 is
connected via one arm 25 to the head-finder circle 19 and via a second arm
27 to a weight 29. When the camera body 3 is vertically oriented, the
head-finder circle 19 is removed from the viewfinder tunnel 5, with the
arm 25 held against a stop 31 by the force of the weight 29. See FIG. 3.
In this instance, if one looks through the viewfinder tunnel 5 at the rear
opening 9, the head-finder circle 19 will not be seen. When the camera
body 3 is horizontally oriented, the head-finder circle 19 is inside the
viewfinder tunnel 5, with the arm 25 held against a stop 33 by the force
of the weight 29. See FIG. 2. In this instance, if one looks through the
viewfinder tunnel 5 at the rear opening 9, the head-finder circle 19
appears to be off-center in the field of view 21 towards another side 34
of the field of view.
The invention has been described with reference to a preferred embodiment.
However, it will be appreciated that variations and modifications can be
effected within the ordinary skill in the art without departing from the
scope of the invention. For example, instead of mechanical means for
positioning the head-finder circle 19 in the field of view 21 when the
camera body 3 is oriented horizontally, electronic means such as
light-emitting diodes can be employed for making the head-finder circle
visible and invisible in the field of view.
